POUNDING-UP ROLL.

Specification of Letters Patent.

Patented Mar. 12, 1912.

Application filed April 27, 1911. Serial No. 623,600.

To all whom t may concern.' Be it known that I, JOSEPH; GOULDBOURN,

a subject of the King of Great Britain, re? siding at Leicester,Leicestershire, England,

have invented certain Improvements in Founding-Up Rolls, of which thefollowing description, in connection with the accompanying drawings, isa specicatio-n, likel reference characters on the drawings indicatinglike parts in the several figures.

This invention relates to pounding up,

leveling or smoothing rolls used in the manufacture of boots and shoes,and particu-l larly adapted for use in re-formlng the boty toms of turnshoes.v

The general o-bject of the present invention is to providean-improvedroll for the purposes above set forth which roll is more effective inoperation and of greater durability than rolls as hitherto constructedfor these particular purposes.

In the roll to which this invention particularly relates there iscombined with the roll body a number. of beating members carried by thesaid body, the said members being arranged to eXert bot-h a pounding-upeffect and a smoothing action upon the surface of the material undertreatment.

According to the illustrated embodiment of the invention the rollcomprises a body part having a number of recesses or slots in which arereceived shank portions of a pluy rality of blocks or beating members.The

shank portions of the blocks or beating members are adapted to slide inthe recesses or slots and under the influence of centrifugal force thesaid blocks are moved to the eXtreme outer position when the roll isrotated. The blocks or the Shanks thereof are provided with projectingparts to engage corresponding parts of the body part to limit themovement outwardly of the blocks when under the. influence ofcentrifugal force and to prevent their disengagement ,froml the roller.When the Ablocks have been depressed against the body part the Wholewill form a circular roller.

Conveniently, the 'body part of the roll may be made up of a number ofdisks placed side by side on a shaft or spindle, each of the' disksbeing providedwlth recesses or slots for the reception of the shanks ofthe beating members. When the body part is thus composed of separatedisks they may each be secured to the shaft or spindle or one alone maybe secured to the said Ishaft the others being loosely mounted thereonand made to revolve with the fixed disk by projections on t-he beat-ingmembers of each disk which projections extend between the adjacentblocks of the neighboring disk and by engaging the sides of the saidblocks impart rotary motion to the loose disk.

` A convenient embodimentof the invention Will now be described by wayof eX- ample and then the invention particularly pointed out in theclaims but it is to be understood that the construction and generalarrangement of the parts may be varied without departing from the spiritof the invention.

In the drawings, Figure 1 is a side elevation of a beating roll` havingcentrifugalbeating elements; is a section through Fig. 1.

In the embodiment of the invention a number of disks 2, forming acylindrical Fig. 2

hub, are mounted upon a shaft 4 and are secured thereon by a collar 5 ato-ne end formed upon or fixed to the shaft. At the 'other end of theseries of disks the shaft is provided with a 'threaded stud upon whichis screwed a nut 6 which through a washer I 8 forces all the disks intocontact. Conveniently the washer may form the inside wall of a plainsurfaced roller` 10 for use in the processof manufacture of a boot orshoe which roll is thus, by means of the same screw, secured to the endof the shaft. Each disk 2 is formed in' one'of its faces with a numberof Vrecesses or slots which conveniently are not disposed radially ofthe roll but are inclined away somewhat from the radius of the roll inthe direction of rotation.` The recesses o-r slots eachreceive the shank12 of a block or beating member which extends from the shank rearwardlyaway from the direction of the v` having, in combination,

part l5 which, at certain times,

which is cut away at the center of the face having the recesses toafford space for the said projections. Sufficient clearance is providedbetween the projecting parts l5 of the shank and the inner surface 16 ofthe disk to permit the blocks to move outwardly to the necessary extentunder the influence of centrifugal force during the rotation of the rollbefore ,the said projecting parts: come int-o engagement with the innersurface of the disk.

Each, or some of the blocks may be provided with projecting parts 18 onone of their faces which engage between the blocks of the nei hboringdisk and thereby insure rotation o the several disks when the shaft isrevolved. When the roll is stationary and the blocks closed in againstthe body part the curved outside faces of the said blocks willconstitute a circular roll. When, however the roll is rotated' theblocks will, under the influence of centrifugal force, be movedoutwardly from the disks as far as is permit-ted by the projections onthe shank and thereby be brought into a position to act upon the workwhich is presentedto and pressed vagainst the surface of the roll.

Having explained the nature of this invention, I claim as new and desireto secure by Letters Patent of the United States l. An apparatus of theclassv described having, in combination, a body roll, com prising anumber of disks placed side by side, a plurality of beating memberscarried by each of the disks, the beaters being arranged to exert both apounding-up and a engage@ l with the inner surface 16 ofthe body part'smoothing action upon, the surface of the` material under treatment andmeans for driving the roll.

having, in combination, nular series of beating wlnchmembers has a shankportion, a body wardly under the infiuence of centrifugal force when theroll is rotated, and means for limiting the outward movement of the`beat-ing members.

3. An apparatus of the class described a body roll having a plurality ofrecesses of annular series of beating members having shank portionsadapted to slide outwardly therein under the influence of centrifugalforce when the roll is rotated, the beating members in saidannularseries beor slots, a plurality -shanks retained in said ingarranged in staggered relationwith one another.

4t. An apparatus ofthe class described having, in combination, a bodyroll having a plurality of recesses or slots, a plurality of beatingmembers having shank portions adapted to slide outwardly therein underthe influence of centrifugal `force when the roll is rotated, thebeating members being arranged in annular series and staggered and eachbeater having a projection eXtend ing laterally across the line dividingit from the neXt annular series.

5. An apparatus of the class described having, in combination, a bodyroll made up of a number of disks placed side by side, each of the disksbeing provided with recesses or slots, beating members having slots, adriving shaft to which one of said disks is secured, and interlockingprojections on the beating elements compelling the other disks to rotatewith the shaft.

6. An apparatus of the class described having, in combination, a bodyroll made up of a number of disks 2 placed side by side, each of thedisks having in one side face a plurality of slots inclined to radiallines of the roll in the direction of rotation, beating members havingbeating heads and relatively thin Shanks sliding in said slotsv andhaving means to limit the sliding movement.

7. An apparatus of the class described having, in combination, a shaft,a collar fast thereon, a beating roll on the shaft adj acent to thecollar, a washer at the opposite end of the roll, a threaded studprojecting from the end of the shaft, a `nut on said stud which throughthe washer clamps the roll against the collar, and a hollow plainsurfaced roller formed on the washer and inj closing the nut. 2. Anapparatus of ythe class described,y a plurality of anmembers, each of-8. An apparatus of the 'cla-ss described having a carrier, and aplural-ity of annular Aseries of beating members, restrained fromforward and backward tipping movement therein, the members of eachseries being yielding independently of the other series and each of thebeat-ing members having a curved leading surface adapted to exert apounding up action upon the surface of the material under treatment, anda relatively long following and'rubbing surface adapted to exert in turna smoothing action upon the said surface of the material.

In testimony whereof, I have signed my name to this specication in thepresence of two subscribing witnesses.
